dna2abc Examples
================================================================

The examples directory contains a few test scripts for
dna2abc.  The scripts end in .tcl, the corresponding
ABC file ends in .abc, and the corresponding MIDI
file ends in .midi.

test1.tcl
	Simple test, reads in.dna and oscillates up or
	down 1 or 2 on A, C, G, or T.

test2.tcl
	Even simpler test, assigns a specific note to
	each base.

test3.tcl
	Oscillates up or down and changes sustain.

findMET.tcl
	Uses a frame of 3 but steps forward by 1 to 
	find the first MET codon, and outputs its location
	to the standard output.  No voices, so no ABC output 
	generated.  This was used to find the skip value
	used in the amino* tests.

amino1.tcl
	Scans in.dna and looks for amino acid codons,
	and does something different for each codon.
	The 3-letter abbreviation of the codon is output
	to the standard output.

amino2.tcl
	Like amino1, but a particular note/sustain is
	played for each codon.

amino3.tcl
	Uses seqfile (see seqfile.tcl in lib-src) to output
	a sequence file containing single-letter codes for 
	the amino acids coded for in in.dna.  The output
	file is out.animo. No ABC output.

protein.tcl
	Demonstrates that nothing about dna2abc assumes the
	input is a DNA sequence.  Reads the out.amino file
	output by amino3.tcl.  The scanner contains no rules,
	but rules could be written to trigger on certain 
	amino acid sequences.
